In my opinion, most of it is pretty terrible. But there are a few shining stars out there, including MC Frontalot and mc chris (Chris performs Oct. 15 at the Waiting Room).

mc chris, for example, is no Jay-Z, but he's pretty good if you like hearing raps about Boba Fett and arcades. Some of the rhymes are genuinely good ("I'm nice, and sweet/and I shower twice a week./Kids diggin' on my speak/cuz I represent the geeks" from "Falynn") while others are just funny ("My backpack's got jets/Well I'm Boba the Fett/Well I bounty hunt for Jabba Hutt/To finance my 'Vette' from "Fett's Vette").

Today marks the release of the documentary, "Nerdcore Rising," which follows around Frontalot on tour and features other nerdcore-ists. It also features interviews with comedian Brian Posehn and Weird Al Yankovic as well as some actual rappers.

There are a few things made clear by the trailer: 1. These guys really are nerds. 2. They're really passionate about what they do. 3. Their fans, also nerds, absolutely love this stuff.
